United States Patent 3,122,354 STUD CLAMP Maurice I. Redcback, R.F.D., Center-ville, Utah Fiied July'24, 1961, Ser.'No. 126,032 '6-Claims. (Cl. 254-131) This invention relates to a novel and useful stud clamp and more specifically to a stud clamp which is specifically adapted for removable engagement with a building stud in order to provide or form alever for straightening a bowed portion of the stud and for establishing a means for rotatably supporting a reel having elongated flexible material wound thereon.

The stud clamp of the instant invention comprises a generally (Z-shaped body including a pair of generally parallel'arms interconnected at adjacentends by means of a bi ht portion disposed at substantially right angles to the arms. The arms each define inwardly spaced abutment means disposed in parallelplanes adapted to engage the opposite side edges of a stud andthe stud clamp is adapted to laterally receive a stud between the arms with one side face of the .stud disposed in surface-'to-surface abutting relation with the inner face ofthe bight portion of "the clamp interconnecting the arms of the clamp. Each of the abutment means is disposed in a plane disposed at an angle relative to a plane perpendicular to and extending between the arms. Alever arm is secured tothe'bight portion of the body and extends in aplane substantially paralleling the medial plane of the bight portionand one end of the lever arm projects outwardly 'of the body. Inasmuch as the abutment means are disposed in two parallel planes which are disposed at an angle relative'to aplane extending between and perpendicular to the pair of'paral lel arms of the body, the C-shaped'body may be'moved laterally of and engaged with a stud with'the stud being received between the arms of the body whereupon'the body may then be rotated about an axis extending at right angles to the'bight portion of the'body and generally paralleling'the arms of the body in order to bring the abutment means into engagement with the opposite side edges of the stud which has one side face disposed in suriace-to-surface abutting relation with the inner surface of the bightportion of the body.

With the stud clarnp thus engaged'with a building'stud, the free outer end of the lever' arm'may be engaged and swung through a plane generally paralleling the plane of the bight portion of the body in order that the-portion of the stud with which the clamp is engaged may be twisted. In addition, the'lever arm extends in a plane substantially perpendicular to the planes in which the abutment means extend thereby insuring that the lever arm will extend in aplane substantially perpendicular to the longitudinal axis of the building stud.

The lever arm is constructed in a manner'whereby it may be readily in effect extended in length by having means carried thereby adapted to engage and support an extension arm-or rod-on-the lever arm'with the extension rod disposed in a plane generally paralleling the longitudinal axis of the lever arm. The extension rod may be utilized to rotatably support a reel having elongated flexible material wound thereon when the stud with which the clamp is engaged is substantially vertically disposed.

A main object of this invention is to provide a stud clamp which may be readily engaged and removed from engagement with a building stud and which may be utilized as a lever arm for use in straightening a bowed portion of the stud.

A further object of this invention, in accordance with the immediately preceding object, is to provide a stud clamp which may be conveniently utilized to rotatably support a reel having a flexible material wound thereon .may be readily and removably engaged with a building stud and utilized as support means for various other components of a building of which the stud with which the stud clampis engaged comprises a part whereby the stud clamp may be utilized-to temporarily support joists, stair risers andzother similar components of a building.

A final object to be specifically enumerated'herein isto provide a'stud clamp which will conform to conventional :forms of manufacture, be'of simple construction and easy .to use so as to provide a device that will be economically feasible, long lasting'and relatively trouble free in operation.

These together with other objects and advantages which will become subsequently apparent reside in the details'of construction and operation as morefully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to likeiparts throughout, and in which:

FIGURE 1 is a perspective view of a fragmentary portion of a vertically disposed stud with the stud clamp of the instant invention shown being moved into position in engagement with the stud by movement of the stud ciamp laterally of the stud;

FIGURE 2 is a perspective view of a fragmentary portion of abuilding stud showing the stud clamp of the instant invention operatively engaged therewith and being utilized to rotatably support a reel having elongated flexible material wound thereon;

FIGURE 3 is a top plan view of the stud clamp;

FIGURE 4 is a vertical'transverse sectional view taken substantially upon the plane indicated by the section line 4-4 of FIGURE 3; and

FIGURE 5 is a vertical longitudinal sectional view taken substantially upon the plane indicated by the .section line 5 "5 of FIGURE 3 with parts of the stud clamp being broken away and the outline of a building stud shown in;phantomalines.

Referring now more specifically to the drawings the nu- .meral'lti 'generaily designates the stud clamp ofthe instant invention which includes a generally C-shaped bodyreferred to .in general by the reference numeral 12. The body'12 includes a;pair of; generally parallel arms 14 and 16 which are interconnected at adjacent ends by means of a bight portion 18. The arms 14 and 16 and the bight portion 18 are formed of one piece of plate material and it will be noted that the ends of each of the arms 14 and 16 remote from the 'bightportion 1-8 terminate in inwardly directed terminal end portions 24) and 22 respectively Which-are each cut away as at 23, generally parallel 'the bight portion 13, which each extend toward the other 'arm of the body 12 and are sharpened at their free ends as at 25.

With attention now directed to FIGURE 5 of the drawings it will be noted that the C-shaped body 12 includes a pair of plate-like elements 24 and 26 defining a pair of abutment means adapted to engage the opposite side edges 28 and 30 of a building stud generally referred to by the reference numeral 32. Each of the plate-like elements 24 and 26 is disposed in a plane which is perpendicular to the plane of the bight portion 18 and is inclined slightly relative to the corresponding arm. The plate-like elements 24 and 26 are substantially parallel and therefore are adapted to engage the opposite side edges 28 and 39 of the building stud 32 in surface-to-surface contacting relation therewith. A lever arm generally referred to by the reference numeral 34 is fixedly secured to the bight portion 13 by means of a suitable fastener 36 and/or welding 38. It will be noted that the lever arm extends in a plane substantially paralleling the medial plane of the bight portion and disposed at substantially right angles to the medial planes of the plate-like elements 24 and 26. In this manner, it will be assured that the lever arm 34 Will be positioned so as to extend along a plane extending at right angles to the longitudinal centerline of the building stud 32. Accordingly, if the building stud 32 is substantially vertically disposed, the lever arm 34 will be substantially horizontally disposed.

It will be noted that each of the plate-like elements 24 and 26 includes a right angled integral plate portion and that these plate portions are referred to by the reference numerals 37 and 39 respectively and are provided with openings 40 and 42 respectively.

The plate-like elements 24 and 26 and the integral plate portions 37 and 39 are each secured between the corresponding arms and end portions of the opposite end portions of the bight portion 18. In this manner, the platelike elements 24 and 26 which are formed integrally with the integral plate portions 37 and 39 are securely fixed within the C-shaped body 12.

With attention now directed to FIGURES 3 through of the drawings it will be noted that the lever arm 34 is tubular and that it is provided with a transverse bore 44 and an internally threaded fastener 46 secured to the outer surfaces of the lever arm 34 with the fastener 46 disposed in alinement with the bore 44. A setscrew or eye 48 is threadedly engaged through the fastener 46 and its inner end may be engaged with the shank portion 50 of a headed fastener 52, see FIGURE 2, on whose shank portion 50 is rotatably supported a drum generally referred to by the reference numeral 54 having elongated flexible material 56 wound thereabout. Accordingly, it may be seen that the clamp It) may be utilized to conveniently rotatably support a drum of electrical Wire or similar material used in building construction.

With attention again invited to FIGURE 5 of the drawings it will be noted that the bight portion 18 has an aperture 53 formed therein which may be utilized to provide a means whereby the clamp may have its body portion 12 secured to the stud 32 by means of a suitable fastener (not shown) such as a nail or screw secured through the aperture 58.

In addition, it may be seen that each of the plate-like elements 24 and 26 includes an inwardly and laterally projecting stud gripping member 60 for frictional engagement with the stud 32. Although the stud gripping members 60 are not required if sufiicient weight is placed on the free end of the lever arm 34, should the weight be removed from the lever arm 34 the gripping members 60 will be needed in order to retain the body 12 of the clamp 10 in position adjusted vertically along an upstanding stud.

It will be observed that the lever arm 34 may be as long as desired or that its effective length may be increased by securing a shank similar to shank 50 therein. Then, the clamp 10 may be utilized to rotatably support a wire reel, to serve as a support for extension arms of workbenches, storage racks, scaffolds, pipe devices, stairtreads and other similar uses.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
